How much does an electrician cost in St. Louis? Based on BLS OEWS May 2024 wage data and RSMeans 2024 construction costs, here are real numbers — not the "$99–$975" ranges you get from lead-gen sites.
Older homes with knob-and-tube or aluminum wiring require complete rewiring, which significantly increases scope and cost.
Every price below is adjusted to St. Louis's labor market using a 1.08× city index applied to RSMeans 2024 national data. Labor hours assume standard conditions — add 15–40% for older homes, difficult access, or code catch-up.
